An Approach to Interpreting Spirometry AAFP

WebThe diffusing capacity for carbon monoxide (DLCO) is a measure of the ability of gas to transfer from the alveoli across the alveolar epithelium and the capillary endothelium to the red blood cells. The DLCO depends not only on the area and thickness of the blood-gas barrier but also on the volume of blood in the pulmonary capillaries. WebWhat is normal lung diffusion capacity? A doctor will take these factors into account and work out a predicted level of diffusion capacity. The normal range for DLCO is as follows: 80–120% of its predicted value for men. 76–120% of its predicted value for women.

Webcardiac output increases in exercise => blood rushes through quickly (only spends 0.25sec in capillary), but normal lung achieves full capacity in that time how does exercise affect DLO2? diffusion rate is 10x greater because of more O2 consumption, but mean capillary P is 1.5x less => DLO2 is 3x more than at rest high urine protein creatinine ratio meaning
